The 283 is a great engine, I think the first to achieve 1hp. per c.i. .
Yes, in 1957, a small number of Corvettes and Bel Airs were fuel injected. They were troublesome but it was a great technological achievement at the time. In 1958 an even smaller number of Pontiac Bonnevilles were fuelies. The few times one of them turn up on a Mechum or Barrett Jackson auction the bidding is astronomical to say the least.
